Abstract: The chromosome numbers and karyotypes of 7 taxa of Delphinium from southern Qinghai in China in the present paper,are reported.Their karyotype formulae are D.pylzowii,2n=16=2m +4sm+10st;D.trichoporum,2n=16=2m+4sm+10st;D.albocoerulum,2n=16=2m+4sm(2SAT)+10st; D.nangchienense,2n=16=2m+6sm+8st; and D.kamaoense var.glabrescens,2n=16=2m+6sm+8st. The chromosome numbers and karyotypes of the former five species are reported here for the first time.

Key words: Delphinium, Karyotype
